Industrial Perforated Dies
Our Industrial Perforated Dies are manufactured from premium vacuum-heat-treated D2, SKD11, and tungsten carbide tool steels, engineered to endure millions of high-impact cycles. Fabricated to achieve CNC micro-punching tolerances (±0.05mm), these dies ensure flawless perforation apertures with zero burrs. They are optimized for staggered 60-degree configurations and complex geometric patterns, delivering extreme wear resistance and extended service life.
Key Features
Premium vacuum-heat-treated tool steels for maximum hardness and wear
CNC micro-punching tolerances (±0.05mm) verified by CMM inspection
Engineered for staggered 60-degree configurations and complex slot geometries
Mill test certifications and heat treatment hardness charts included
